The whole world is reeling after a milestone referendum in Britain to leave the European Union. And although leaders of the campaign to exit Europe are crowing over their victory, it seems many Britons may not even know what they had actually voted for.

Awakening to a stock market plunge and a precipitous decline in the value of the pound that Britain hasn't seen in more than 30 years, voters now face a series of economic shocks that analysts say will only worsen before they improve. The consequences of the leave vote will be felt worldwide, even here in the United States, and some British voters say they now regret casting a ballot in favor of Brexit.

Even though I voted to leave, this morning I woke up and I just — the reality did actually hit me," one woman told the news channel ITV News. "If I'd had the opportunity to vote again, it would be to stay."

That confusion over what Brexit might mean for the country's economy appears to have been reflected across the United Kingdom on Thursday. Google reported sharp upticks in searches not only related to the ballot measure but also about basic questions concerning the implications of the vote. At about 1 a.m. Eastern time, about eight hours after the polls closed, Google reported that searches for "what happens if we leave the EU" had more than tripled.
